{"schemaVersion":3,"id":"CVE-2026-105766","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Use of the backend-facing $scheme variable in the trailing-slash directory redirect in nginx.conf of Chainguard Academy (edu) from commit 0b75ff98057f69b044a3e7194e428066ac5ad0d4 before commit 93dc0e50739c225f5aee2e803800a47fc0feb906 allows an on-path network attacker to read or modify documentation content served to a victim via an HTTPS request for a slashless directory path, because TLS terminates at the load balancer in front of Nginx and the resulting 301 response redirects the client to a plaintext http:// URL. Browsers that ship the HSTS preload list are not affected, because the .dev top-level domain is preloaded; clients that do not enforce HSTS, such as command-line HTTP clients and scripts that follow redirects, are affected.","dates":{"published":"2026-10-05T19:45:50.015Z","modified":"2026-10-06T13:44:09.303Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":3.1,"severity":"low","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:L/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"4.0","versionLabel":"v4.0","source":"CVE.org","score":2.3,"severity":"low","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":3.1,"severity":"low","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:L/A:N","exploitability":null,"impact":null,"computed":false},{"version":"4.0","versionLabel":"v4.0","source":"NVD","score":2.3,"severity":"low","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":3.1,"severity":"low","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:L/A:N","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00106,"percentile":0.01047,"severity":"low","asOf":"2026-10-20T00:00:00.000Z","change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[{"date":"2026-10-06T00:00:00.000Z","score":0.00106,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00106,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00106,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00106,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00106,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00106,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00106,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00106,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00106,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00106,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00106,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00106,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00106,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00106,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00106,"percentile":0.01047}],"last30":[{"date":"2026-10-06T00:00:00.000Z","score":0.00106,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00106,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00106,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00106,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00106,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00106,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00106,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00106,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00106,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00106,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00106,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00106,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00106,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00106,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00106,"percentile":0.01047}]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[{"id":"CWE-319","name":"Cleartext
